SPARK ultra-wideband products solve the problems of power, data rate, latency, and link robustness that limit existing short-range narrowband wireless solutions.


Wireless Transceivers

wireless transceiver

The SPARK SR1000 UWB IC series takes full advantage of ultra-wideband (UWB) technology to simultaneously deliver industry-leading energy efficiency, latency and bandwidth:

  • Data rates of up to 6 Mbps @ 1.5 nJ/bit energy efficiency
  • 2 mW power consumption while transmitting and receiving 1 Mbps, scaling to 6 uW at 1 kbps
  • Ultra-short wireless latency (50 µs for 1 kb)
  • Time-of-flight positioning

The SPARK SR1000 series consists of two products:

  • SR1010: 3.1 – 5.8 GHz band
  • SR1020: 6.0 – 9.3 GHz band

Software Development Kits

SDK Spark microsystems



The SDK is an extensive software suite for the SR1000 Series UWB transceivers. It can be used to simplify and accelerate development for applications such as establishing communication links between two transceivers for low latency, low power data exchange and time-of-flight ranging.

Hardware Kits



The SPARK SR1000 Series Evaluation Kit is meant to demonstrate the capabilities of the SR1010 and SR1020 low power, high data rate radio transceiver family. It allows users to benchmark the SR1000 family’s unique qualities in terms of data rate, power consumption, and latency according to different configurable presets.

SPARK SR1000 Family Evaluation Kits Features:

  • Low latency audio streaming demonstrator:
    – 5 ms latency uncompressed 48 kSps 16-bit stereo
  • Wireless link quality statistics
  • Power and latency monitoring
  • Time-of-flight positioning demonstrator
  •  Advanced mode for customization
  • Battery-less sensor nodes
